Abstract

Plasmas in edge regions of tokamaks can be very optically thick to hydrogen lines. Strong line radiation introduces a non‐local coupling between different regions of the plasma and can significantly affect the ionization and energy balance. These effects can be very important, but they are not included in current edge plasma simulations. We report here on progress in self‐consistently including the effects of a magnetic field, line radiation and plasma
transport in modeling tokamak edge plasmas.
